      Lung Cancer is the leading cancer killer in United States
      Leading cancer killer in men and women in United States (29% of all cancer deaths)
      219,440 new cases of lung cancer in 2009
      159,390 deaths from lung cancer
      5 year survival rate in patients with lung cancer is less than 15.2%
    • 9. Types of lung cancer
      The two main types of lung cancer are:
      Small Cell Lung Cancer (SCLC)
      about 10% of all lung cancer patients are of these type
      Non Small Cell Lung Cancer (NSCLC)
      about 80-90% of all lung cancer patients are of these type
      Other types of tumors include Lung Carcinoid Tumors, whichare slow growing and can be cured by surgery.
    • 10. Types of Non Small Cell Lung Cancer (NSCLC)
      The 3 sub-types of NSCLC differ in size, shape, and chemical composition.
      About 40% of lung cancers.
      Usually found in the outer part of the lung
      Squamous cell carcinoma: 
      About 25% to 30% of all lung cancers are this kind.
      Usually develops in the middle of the lungs, near a bronchus.
      Large-cell (undifferentiated) carcinoma: 
      About 10% to 15% of lung cancers are this type.
      It can develop in any part of the lung.
    • 11. Symptoms of NSCLC
      Persistent cough
      Trouble breathing
      Chest discomfort
      Streaks of blood in sputum
      Loss of appetite

    • 12. How is NSCLC diagnosed?
      Physical exams
      Laboratory tests

    • 90. Confidence Interval
      Expected range of outcome: a range of statistical values within which a result is expected to fall with a specific probability

    • 91. Hazard Ratio
      How often a particular event happens in one group compare to how often it happens in another group, over time. In cancer clinical trials it measures survival at any point in a group of patients who have been given a specific treatment compared to a control group given another treatment or a placebo. A hazard ratio of one means that there is no difference in survival between the two groups. A hazard ratio of greater than one or less means that survival was better in one of the groups.
